The model above shows an A nucleotide being substituted with a C nucleotide. Which statement explains how the change in DNA leads to the sickle cell disorder?

• The deletion mutation causes a different amino acid to be removed; preventing the production of the hemoglobin protein in the body.

• The point mutation causes a different amino acid to be replaced; preventing the hemoglobin protein from functioning properly.

• The frameshift mutation prevents the production of several proteins found in the blood.

• The insertion mutation causes extra hemoglobin proteins to attach to red blood cells.

Based on the data they collected above, which of the following claims and supporting evidence statements would be a reasonable conclusion the biologists could make?

• CLAIM: The function of the overall protein will not be affected by the insertion mutation. Evidence: The change in the DNA from a T to a C still codes for the same amino acid Tyr.

• CLAIM: The function of the overall protein will be affected by the frameshift mutation. Evidence: The change in the DNA from a T to a C still codes for a different amino acid Tyr.

• CLAIM: The function of the overall protein will not be affected by the silent mutation. Evidence: The change in the DNA from a T to a C still codes for the same amino acid Tyr.

• CLAIM: The function of the overall protein will be affected by the silent mutation. Evidence: The change in the DNA from a T to a C codes for a different amino acid Tyr.

Use the genetic codon chart to determine how this difference affects the sequence of amino acids in the resulting protein.

• Phe in person A is replaced with Leu in person B.

• A STOP codon is generated in person B and not person A.

• Lys in person A is replaced with Glu in person B.

• Person A and B have identical amino acid sequences.
